Summary
A 4 m tall, 0.35 m deep solar chimney with a reinforced-concrete absorber wall is simulated in two dimensions using a k-ω turbulence model with coupled conduction, convection and radiation, checked against published cases and an experiment. Varying ambient temperature, irradiance and Reynolds number yields correlations for the total Nusselt number, and heat transfer from the heated wall rises with Reynolds number.
